MyGeoTrails allows you to mark places of interest on the map along the trail created by the app and share them on Facebook if you wish. You may even share the complete trail with the click of a button. Use retrace mode to travel back on a trail already created before.
The app records your GPS locations periodically when you press the start trail button. The information is stored only in your phone. When you explicitly share your trail information, only then is the information moved around on the Internet.
